Sgt. Van Blankenstein  STS-22   29-12-43.

This student arrived unexpectedly on Tuesday evening 21-12-43. Party and school number unknown. No information available. he told me that he was sent here on a short course to learn the first elements of arthritis and that he done the rest of the training. On Thursday 23-12-43 he wrote two letters, which were two examples on bad security.
The first one addressed to Mr. Biallosterske, ran as follows; "You will probably think that this is a peculiar way of starting a letter, no date .. and no heading, but it is better to do so for this time
The work I'm doing is very hard but healthy. At night time I am very tired and only want to get in bed early, because the day's work is long My journey was anything but quick. I only arrived at Glasgow at 10 p.m. and the connection I had to catch had already left a long time ago. The next train was only at 6 a.m. on Tuesday morning and this is the only train of the day. I did not get bored because the town is very pleasant and I had a first class hotel. I arrived exactly a day late at my destination . Don't forget to answer my letter because I am cut off from the whole world..."
The second one addressed to Mrs. Costa, sais: "You are perhaps curious about certain things. It is not possible for me to tell you anything about them here and certainly not in a letter.." Mrs. Costa is his cousin. He has only seen her once before, but hopes to meet her soon. As he is a commissioned officer, I asked Lt. Tivey to make the necessary remarks, which he did in my presence. I explained to him afterwards the reason for our precautions and he agreed that our security measures were necessary. He re-wrote the two letters later on and they were posted at STS HQ on 27-12-43. Please let me know if I have to take any further interest in this student.

STS-51   4-12-43.

This officer was quite fit on arrival and worked hard during the P.T. and ground training. He seemed quite confident and cheerful and carried out the course in good style. He made four descents - two from aircraft and one from a balloon by day and one from an aircraft by night. He participated in the night exercise. Showed himself to be a serious modest type, correct in his demeanour and one who took full advantage of the instruction with excellent results.

Sgt. Van Blankenstein STS-22    4-1-44.

Left for London on 30-12-43.

D/CEM.3 to NP  13-1-44.

I understand that this student was withdrawn from STS-22 on 30-12-44 and is now in London awaiting a mission.
In view of this, your attention is drawn to FSP report dated 29-12-43 which seems to indicate that his security mindedness is not all that could be desired.

STS-40   2-3-44.

Qualified to operate and maintain S-Phone in the field, providing he uses his own

Fair. Competent but more experience advisable.
R.C. work         
Has worked very well and has a sound knowledge of the subject.
C.O. remarks      Recommended.

STS-39  23-3-43.

This student was here only for three days. During that time an attempt was made to give him, in a very condensed form, a great deal of instruction over a wide variety of topics. Quite apart from the shortness of time, it was difficult to judge his capacity, owing to the fact that his English is poor and that he shared no alternative language with his instructor. Nevertheless, he is evidently keen about the whole subject; and he has a very pleasant personality and his mental bent is evidently practical and business like. He knows what he wants to do and will use common sense rather than detailed political and theoretical knowledge to get it done.

Remarks        A young man with a far better intelligence than his rating indicates. His carelessness and lack of
                     forethought spoilt nearly all his work. He is alert, quick and showed both resource and ingenuity. In
                     addition, he is sincere, patriotic, warm and friendly in manner and anxious to return to the field as
                     soon as possible. He is immature, opinionated, has far too much youthful self confidence, even
                     conceit and is not likely to prove very amenable in training. He needs discipline and a full rigorous
                     course of training is recommended. His work in the field has been good in subordinate capacity and it
                     probably represents the limit of his suitability.

Country Sect. This man has been selected for a special mission of limited duration which can only be carried out by
remarks         someone already known to persons in the field who have to be contacted. As the knowledge he
                     already has is considered sufficient for his task, his training will be curtailed accordingly.
